through the steps needed to input your credentials into the Virtual Earth
LiveObjects used in the demo.  It assumes that you have already obtained
your credentials from Microsoft.  If not, <A HREF="https://mappoint-css.live.com/MwsSignup/">

<P STYLE="font-weight: normal"><FONT SIZE=3>C:/liveobjects/examples2 contains 3 files that need
credentials to use them: map_aerial.liveobject, map_road.liveobject, and map_traffic.liveobject.
This is because they use Microsoft's <A href="http://msdn.microsoft.com/en-us/library/bb507684.aspx">
Virtual Earth</A> service, which requires that all users have valid credentials.  We have our own
account for development, but for now all users need separate accounts.  Once you have an account, follow
these steps to setup the Liveobjects:</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>1. Open <b>c:/liveobjects/examples</b> and
<b>c:/liveobjects/examples2</b>.  These folders contain the necessary Liveobjects.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>2. From <b>examples</b>, double click on 
<b>object_designer.liveobject</b> to open the object designer.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>3. Drag 1 of the 3 objects (map_aerial, map_road, or map_traffic)
into the center panel of the object designer.  The designer should now show a rectangle in the center
panel, as well as some text in the left panel.  If you double click on the rectangle in the center
panel, VE Aerial Map, you should see another rectangle, Tiled Map Manager.  Each of these rectangles
defines a different Liveobject.  The lines connecting them indicate communication through interfaces.
Finally, double click on <b>Tiled Map Manager</b> and two new rectangles should appear.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>4. Click on the leftmost object, MSN Virtual Earth.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>5. You should see a tree of objects/properties in the left
panel.  One item should be highlighted in yellow.  This is the currently selected object-- in our case
, the MSN Virtual Earth object.  It is responsible for communication with Microsoft's servers and is
also the object that requires credentials.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>6. Expand the highlited entry, <b>Predefined Object "MSN Virtual Earth"</b>.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>7. Right-click on <b>Parameter "MSN VEarth Username"</b> and click <b>Change Value</b>.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>8. In the box that appears, enter your MSN username and hit <b>Enter</b>.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>9. Now right-click on <b>Parameter "MSN VEarth Password"</b> and click <b>Change Value</b>.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>10. In the box that appears, enter your MSN password and hit <b>Enter</b>.</FONT></P>
<P STYLE="font-weight: normal"><FONT SIZE=3>11. You're done.  All that is necessary now is to save the file.  
This is done in a slightly unique way.  You must click on the root of the tree, <b>Predefined Object "VE Aerial Maps"</b>
and drag it to a  folder of your choice.  The video above uses the desktop for convenience.  You may then
rename the file to something more convenient. <b>NOTE:</b> Be sure to leave the .liveobject extension or
your Operating System may not recognize the file.</FONT></P>
